In Figs. 5-7 the dimensionless transversal displacement is plotted against the dimensionless axial coordinate , x L when 05 . ξ = , for the three examined values of θ . In each Figure, the case of an intact nanobeam (that is, 00 . ξ = ) is also reported. It can be observed that the maximum value of deflection is found when the crack angle is equal to 0 .0. °
